Wadia S7i vs Esoteric K-01/K-03 vs MSB


As I want to upgrade from Sony XA5400ES has someone compared the following:

-Wadia S7i
-Esoteric K-01 or K-03
-MSB with Platinum Dac IV plus, Signature Platinum Power Base, Upsampler 384 kHz and Platinum dac IV transport or any other MSB device.

I got already a great deal on a used Wadia S7i, which however is discontinued now.
I have no possibilities to compare any of these and apparently there is no specific information available on the net.

Thanks for making any efforts.

One thing I did not mention on MSB that you might want to consider is their new Analogue DAC starting at $8K and going up with additional inputs and the upgraded power base.

I heard it at Newport show and it is very good sounding piece that is a good value if you use it to replace a pre amp.

It goes to 384 khz and I believe will also do DSD files.

With their Universal transport for SACD, you would be in the $15K range with a couple extra digital inputs. Add $3K if you want the upgraded power base.
Mallen123 and Matjet@ Thanks.
I got a great deal on the MSB, so the price is more or less the same as the K-01.
I think I could live easily with one of them as I think both are excellent, but comparing them directly proved difficult however.
The more versatile package of MSB, eg. adding the superior clock they offer later or upgrading to the better dac-options, seems the more interesting solution.
Sequence,

The ablility for an upgrade path is what swayed me to the MSB DAC IV Signature. I paired mine with the Universal Media Transport and it sounds fantastic.
Audiolabyrinth,

That is what I want to know also, which is the best or what are the differences! Not possible to compare here.
Both brands are ebullient recommended by its customers.
